Brain’s view of motion is not so simple
NYU (US) — The relationship between the brain and visual perception varies depending on the type of motion being viewed, a finding that suggests a significantly more complex process than previously thought. Continue…

Illusion explains how we view motion
STANFORD (US) — Flies like watching computer screens as much as the next animal. Set them on a trackball in front of a monitor, and they’ll follow the action. (more…)

Driving game maps brain’s version of GPS
U. PENN (US)—Using implantable electrodes and a first-person driving game, researchers have identified the brain cells that indicate travel in a clockwise or counterclockwise motion, called “path cells.” (more…)

Scans show brain’s 2D region processes 3D
Bas Rokers (pictured), Alex Huk, and Larry Cormack discovered the center for 3D motion processing in the human brain. An enhanced image of Rokers’ brain from an fMRI scan shows the region active when perceiving 3D motion, seen as the bright blue area in the lower left of the photo. (Credit: Marsha Miller/UT Austin)

Slithery science of snake movement
How does an animal move without legs? Animals without legs tend to be long and slender, such as the corn snake above. This allows them to squeeze into spaces under branches and leaves. To move along flat ground, snakes use a variety of limbless “gaits,” analogous to those of the horse, such as the walk, trot, and gallop.

Dogs are efficient, but stealthy cats get prey
DUKE (US)—Evolution can behave as differently as cats and dogs. While dogs depend on an energy-efficient style of four-footed running over long distances to catch their prey, cats seem to have evolved a profoundly inefficient gait, tailor-made to creep up in slow motion on a mouse or bird. (more…)
